quote:Originally Posted by irpsitI think the most important this event will be even heavy precipitation and thunderstorms.

The wind will also be violent for a few hours, but I do not think anything extraordinary (except tornadoes possible).

Ainds recall that a pressure 980mb is not at all uncommon in Portugal. Atlantic depressions may reach even much lower pressures, up to 930mb. 980mb is not enough. However if there is enough pressure gradient, wind can always be stormy.

I do not believe that an event is going to be very cold after the passage of depression. Snow in the highlands, but nothing unusual for a situation January.

The lower the latitude is more difficult to withstand low pressure atmosphere that order. A depression of 975 here probably corresponds to one of 960 or less in Iceland, or something like that. And beyond the minimum pressure, which by itself does not tell all, the way is tight gradient is very important, and especially the speed at which the pressure falls, the process to be explosive or not. The risk is there, not the pressure value is x or y. In some models the process is more aggressive, more moderate in another, so we can have a normal winter time as may happen in some place possibly something more extreme. [link to www.meteopt.com]

Sixteen districts of mainland Portugal are under notice orange and two yellow due to the forecast of rain and strong winds and rough seas, according to the Portuguese Institute for Ocean and Atmosphere (IPMA).

The districts of Viana do Castelo, Porto, Vila Real, Braga, Bragança, Aveiro, Leiria, Viseu, Guarda, Castelo Branco, Coimbra, Lisbon, Setúbal, Portalegre, Beja and Faro are under orange alert due to the forecast between now and Saturday precipitation and strong winds that the highlands can reach 120 km / hour, and rough seas with waves between 4 to 5 meters.

The IPMA put the districts of Évora and Santarém under yellow alert, the second least severe of a range of four, due to the forecast of rain sometimes strong between 03:00 and 08:59 on Saturday.

Also under yellow alert is the Madeira archipelago due to the forecast of strong winds with gusts of around 90 km / hour in mountainous and rough seas with waves between 4 and 5 meters.

For this Friday, the IPMA provides, in the north and center, cloudy, rain, sometimes strong especially from the late, weak to moderate wind from the southwest, becoming strong to very strong in the highlands with gusts around 120 km / hour and a small temperature rise.

In the south, the forecast shows cloudy, periods of light rain, increasing in intensity and frequency from the late, weak to moderate wind becoming southwest of moderate to strong with gusts of around 70 km / hour on the coast from the afternoon.

In the highlands, the moderate to strong wind will blow from the west, with gusts of around 95 km / h becoming southwest, and may blow strong to very strong with gusts around 120 km / hour in the Serra de S. Mamede, and fall short of the minimum temperature.

The National Authority for Civil Protection advises citizens to adopt precautionary measures to ensure the roads and clearing systems with drainage due to bad weather forecast for the next 48 hours.

Following the warning, which predicts a worsening of the weather in the next 48 hours with strong winds, rain and rough seas, the National Authority for Civil Protection (ANPC) draws attention to the expected effects of the weather situation as groundwater, slippery surfaces and the possibility of flash floods in urban areas, by accumulation of rainwater or drainage systems weaknesses.

Bad weather can also cause "flooding by overflow of water lines in the historic areas most vulnerable to damage structures mounted or suspended, accidents and flooding in coastal urban structures with underground drainage deficiencies."

The ANPC states in its website that the possible impact of the effects of bad weather can be minimized, especially by adopting appropriate behaviors.

To avoid serious situations, the ANPC advises citizens to ensure clearance systems stormwater runoff and removal of inert and other objects that can be dragged or create barriers to the free flow of water and ensure adequate fixation of loose structures, including scaffolding, placards and other overhead structures.

With regard to driving, the ANPC advises motorists to adopt defensive driving, slowing down and taking special care with the possible formation of ground water on the roads, not cross flooded areas, so avoid the entrainment of people or vehicles for holes in the floor drain or open boxes, be careful in circulation along the shoreline and riparian zones and not doing activities related to the sea.
